Wiki info about Beaufighter Mk X

A design rapidly born from the wings and tail of the earlier Beaufort, the Beaufighter was a two seat, twin engine heavy fighter designed for long range, ground strike and night fighter duties. Equipped with an early AI radar, the Beaufighter was one of the world’s first successful night fighters.
Most of the last mass-produced aircraft in Britain were Beaufighter TF Mk Xs. This model was a logical continuation and development of the Mk VIC, had two Hercules Mk VI engines optimised for low level flight, and could carry the standard torpedoes produced in Britain and the United States. The TF letters in the designation stood for “Torpedo Fighter”. The aircraft could also carry a bomb load of 1100 kg, and with the help of an AI Mk.VIII radar installed in a ‘thimble’ nose, they were highly capable machines employed in detecting and destroying surface shipping. In the Far East the Beaufighter was reputed to be nicknamed ‘Whispering Death’ by Japanese soldiers, although some modern historians believe this to be Allied propaganda.
In March 1945, over a period of 48 hours, Beaufighter TF Mk Xs of No 236 and No 254 Squadrons found and destroyed five German submarines.
The last major variant of the Beaufighter, over 2200 were built in Britain.
